What gives Irish Stout its character

These structural drivers help shape its characteristic sensory profile.

  • Very high roast level creates very dark colour, intense roast flavour, firm bitterness and a pronounced roasted character dominating the malt profile.
  • Early-boil-focused hopping strongly increases IBU and perceived bitterness and can lengthen the bitter finish.
  • Finings remove suspended yeast and protein, improving clarity.
  • Low crystal usage slightly increases colour, body, sweetness, finish length and caramel-like malt aroma.
  • Roasted barley produces intense dry roast and stout-like character.
  • Melanoidin malt adds intense maltiness and strong melanoidin aroma.

History
